Chop up your carrots, mandarin/ orange and sweet potato into chunks, small enough for your blender to handle. Add the turmeric.
Add in a scoop of protein powder, should you wish. Any flavour is fine, but vanilla is a good base for all smoothies. Add your apple juice and your almond/ oat milk.
Blend for 30 seconds/ 1 minute, until desirable mixture. Pour into your chosen bottle, or screw on the lid and enjoy.
